Lokesh Jain updated HUDI-6660:
------------------------------
Description: Currently merge into fails when primary key is a complex key
and join conditions do not include all the primary key columns. The Jira aims
to restrict the constraint only when optimized writes are enabled. With the
optimized writes disabled, merge into doesn't update the records if the primary
key does not match completely. (was: Currently merge into fails when primary
key is a complex key and join conditions do not include all the primary key
columns. The Jira aims to relax this requirement to allow join even on a subset
of primary key columns.)
> For merge into use primary key constraint when optimized writes are enabled
